bistoury

The cardinal had his perineum opened by La Peyronie's bistoury; but he might have confessed and communicated before the operation.

This done, a clean incision is made with the bistoury or the scalpel in the direction of the vessels.

This should be picked up with the forceps, and a further incision made with the bistoury.

This, if a fistula is present, may be best done with a blunt-pointed bistoury, or with a cannulated director and a scalpel.

Perhaps the most heroic consists in opening the joint capsule with a bistoury or with the actual cautery.
